Laser printers work by creating latent images on a rotating, light-sensitive drum and then attracting toner to exposed points on that drum. If any point on the drum’s light-sensitive surface is damaged, you may notice that toner is always attracted to that point, thereby transferring to the final page and appearing as a repeating mark. Because the drum is a cylinder, such marks will appear at equal distances down the page, corresponding to each rotation of the drum (maybe every two inches, for example).

The only solution to this problem is to replace the drum. For most low-cost home printers, the drum is part of the toner assembly and is automatically replaced each time you install a new toner cartridge (which explains part of the cartridge’s high cost). More industrial-strength laser printers place the drum on a separate EP (electrophotographic) “engine” that can be replaced in just a few easy steps. Check your printer’s documentation and replace the appropriate assembly (or have someone do it for you), and the repeating marks should go away.

Kindly regards,
micromaster

Dear user of Brother HL-2040,

Micromaster was correct to explain the mechanism of drum. Since Brother HL-2040 is a low cost home printers, the drum is seperated from the toner and the drum unit.

You have replaced the drum but if you are handy enough, do take out the fuser assembly and try to clean it up too since some toner are very sticky to the Fuser Assembly. Fuser Assembly for this unit is located almost at the back of the printer and consist of two(2) rotating drum. Orange colour for the Rubber Roller and Dark Color for the Heating Drum.

To take it our, you need to do the following:-
1) remove the rear cover
2) remove the side cover
3) remove the top cover
4) remove the black paper guide at the back of the printer
5) remove the white paper guide at the top of the fuser assembly.
6) remove the fuser assembly (2 screws) and the cables white cable on one side and grey cable attaching to the other side of the fuser assembly.
7) Clean the fuser assembly.
8) reinstalled them.

Taking out the paper guide cover is tricky since you need to take out at a certain angle.

Buy a real laser printer and stop buying the cheapest thing you see. (it always cost more in the end and soon your end may be too sore to bare it)

SOURCE: have black smudge line in middle of paper have new toner and drum

Try taking out your toners, and on the drum you will see a green button which you can slide from side to side (it's on each of the colored slots). Make sure you put the the white plastic cover up and then it will slide. I hope this will help you.

What causes my copier pages to have black smudges on them.


Black smudges are usually caused by a defective or worn out drum. When the drum gets a fingerpirnt, any kind of oil, or anything else that causes the static charge to not hold the toner to the paper, the toner will not go where it is supposed to in order to create the image on the paper and it will cause smudges, streaks or lines.

Black lines on paper


Dots, Lines and smudges on the printouts are due to deteriorating cartridges and cleaning the green drum of the cartridge may help temporarily. Take out the cartridge and gently clean the roller/ green drum with a dry, soft, lint-free cloth wiping off the toner dots marks/ lines.
Also, make sure that the visible inside of the printer is clean and ther is no spilled toner inside, which sometimes results in dots.
Let me know if any further clarification/ assistance is required.


GoodLuck!
Dont forget to appreciate the solution if I could have been of any help!

Black smudges down left side of page


How do I clean white or black spots on printed documents? Description: First make 10 to 15 copies of a blank, white sheet of paper.
If you still see the spots on printed documents after making multiple copies, clean the drum unit as follows:

  1. Remove the drum unit and toner cartridge assembly, and then remove the toner cartridge from the drum unit.
  2. Position the print sample in front of the drum unit so you will know the exact position on the drum that is causing the poor print.
  3. all-ug-19.gif
  4. Turn the black gear on the drum as you check the surface of the OPC drum.
    The OPC drum is photosensitive so do not touch it with your fingers.
  5. all-ug-20.gif
  6. When you find the substance on the drum surface that matches the print sample, gently dab the surface of the OPC drum with a cotton swab that is lightly dampened with isopropyl alcohol.
  7. Note
      • Do not use a scrubbing or wiping motion because this might damage the drum.
        all-ug-21.gif
      • Do not try to clean the surface of the OPC drum with a sharp object, such as a ball-point pen, because this might cause permanent damage to the drum unit.
  8. If the print quality still has not improved you need to install a new drum.

Prints are having black lines and smudges along the sides of the paper. What do i need to clean?


Unfortunately when it comes to toners and drums there isn't much that can be fixed with cleaning. It sounds like either your toner cartridge is worn or defective and spilling toner, or your drum could need replacing and therefore is acting up. To check if it's the drum, pull out the drum unit and look at the drum roller (but don't touch it!) you should see streaks or color changes on the roller in places matching where the smudges on the paper are if the drum needs to be replaced.

My bet is on the drum. Drum units are fairly easy to get a hold of, since it is a "replaceable" part of the printer. And if you can install the toner you should do fine with the drum unit as well.

Hope this helps, good luck!
